Researchers have claimed that listeners tolerate large temporal distortion when integrating the spectral components of speech. In some estimates, perceivers resolve linguistic attributes at spectral desynchronies as great as the duration of a syllable. We obtained new measures of perceptual tolerance of auditory asynchrony, using sine-wave synthesis in(More)
Speech signal components that are desynchronized from the veridical temporal pattern lose intelligibility. In contrast, audiovisual presentations with large desynchrony in visible and audible speech streams are perceived without loss of integration. Under such conditions, the limit of desynchrony that permits audiovisual integration is also adaptable. A new(More)

FLY is a parallel treecode which makes heavy use of the one-sided communication paradigm to handle the management of the tree structure. In its public version the code implements the equations for cosmological evolution, and can be run for different cosmological models. This reference guide describes the actual implementation of the algorithms of the public(More)

The Cosmo.Lab project, financed by the European Community , has the object of developing AstroMD, a tool of visualization and analysis of astrophysical data. AstroMD responds to the requirements proposed by several research fields: data coming from cosmologi-cal simulations, from observational catalogues and extended objects like radiosources or clusters of(More)

Over the past few years, the role of visualization for scientific purposes has increased enormously. In Astronomy the visualization techniques are so frequently applied to analyze data that they now represent a fundamental part of the modern researches in Astronomy. Since the evolution of high performance computers, the models and the simulations based on(More)
This study examines the relative contribution of biological and psychological processes to the induction of panic attacks by a biochemical challenge agent. Panicogenic doses of caffeine were administered to 8 panic disorder (PD) patients and 11 healthy volunteers during stage 3-4 sleep, when cognitive processing is minimal and the threshold to external(More)
